摘要

目的探讨使用自体髂骨及桡骨头作移植物重建伴顽固性肘关节脱位的巨大冠突缺损，以恢复关节稳定性的临床疗效。方法回顾性分析采用自体髂骨或桡骨头移植物重建严重冠突缺损的6例患者的临床疗效。患者平均年龄36.2岁（28~57岁）。所有患者均因创伤导致严重冠突缺损伴陈旧的顽固性肘关节脱位，存在关节面磨损、塌陷及创伤性关节炎表现。结果 6例患者从受伤至重建手术平均时间间隔为26.8月（11~60月）。其中，5例患者取自体髂骨作移植物，1例取自体桡骨头作移植物。手术同期，2例接受桡骨头置换，2例采用Box-loop法重建侧副韧带，1例重建外侧副韧带。平均随访时间为26.5月（1~88月）。术后复查CT显示，术后超过3月的5例患者均实现骨性愈合，1例出现移植物吸收。5例患者术后仍遗留一定程度的肘关节僵硬；其中3例2期接受肘关节镜松解手术，2例功能恢复较为满意。6例患者的梅奥肘关节功能评分术后均较术前显著改善。结论采用自体髂骨及桡骨头移植物对伴顽固性肘关节脱位的冠突大面积缺损进行重建，能够获得确切的骨性愈合及关节复位并长期维持；结合2期关节镜松解手术，能使患者肘关节功能满足日常生活需求，避免关节置换，改善患者预后。

Abstract

Objective To evaluate the clinical efficacy of using autologous iliac bone and radial head grafts for the reconstruction of massive coronoid defects associated with persistent elbow dislocation to restore joint stability. Methods A retrospective analysis was conducted to evaluate the clinical outcomes of 6 patients who underwent reconstruction of severe coronoid defects using autologous iliac bone or radial head grafts. The patients had an average age of 36.2 years (28-57 years). All cases involved severe post-traumatic coronoid defects with chronic elbow dislocations, characterized by significant articular surface damage, collapse, and severe post-traumatic arthritis. Results The average interval between injury and reconstructive surgery for patients was 26.8 months (11-60 months). 5 patients received autologous iliac bone grafts, and one patient received an autologous radial head graft. Among them, 2 patients simultaneously underwent radial head replacement, 2 underwent Box-loop reconstruction of the collateral ligaments, and one underwent lateral collateral ligament reconstruction. The average follow-up duration was 26.5 months (1-88 months). 5 patients who were followed for more than 3 months, have achieved bony union according to CT scan. One case exhibited graft absorption. Residual elbow stiffness was observed in 5 patients postoperatively, 3 of whom underwent secondary arthroscopic elbow release, with 2 achieving satisfactory functional recovery. All patients demonstrated significant improvement in the Mayo Elbow Performance Score compared to preoperative values. Conclusions The use of autologous iliac bone and radial head grafts to reconstruct massive coronoid defects associated with persistent elbow dislocation has demonstrated reliable bone healing and joint stability, with a low incidence of joint re-dislocation or graft absorption. Combined with arthroscopic release procedures, this operation can restore elbow function to meet the demands of daily activities, obviate the need for joint replacement, and improve patient outcomes.
